The celebrity couple took their appeal to the Supreme Court in an attempt to remain anonymousGetty Images

The famous couple behind the so-called celebrity threesome injunction will remain secret in the English and Welsh press, for the time being at least, after the Supreme Court reserved its judgement on whether the banning order should be lifted. The Court of Appeal received an application from The Sun On Sunday newspaper, who sought to publish a story revealing the exploits of the "well-known" man at the centre of the injunction.

The individual at the centre of the injunction, known only as PJS, then counter challenged this appeal at the Supreme Court after three Court of Appeal judges ruled in favour of the tabloid's publishers, News Group Newspapers, that the celebrity couple should be named.

After hearing a challenge from PJS's legal team to keep the privacy injunction in place on the basis that revealing their identity would be "devastating" for the children, five Supreme Court justices announced that it would reserve judgement and give its decision at a later date. The injunction barring his name being reported still remains in place.

The man at the centre of the gag has already been named in a Scottish newspaper, a UK-based blog, as well as in the press in the US and Sweden. The celebrity couple were also successful in getting Google to remove links to articles in which they were named as part of the privacy injunction.

The Sun On Sunday attempted to justify running the story after arguing that the couple had put "many details" of their relationship in the public domain.
